What's New?

Is it New Bike Time? Always!
05/22/19- Don't waste another nice day on impulse power when you could be riding at Warp 9. Chain Reaction features the very best bikes from Trek & Electra, as well as the highest-quality travel bikes from Bike Friday. Road, Mountain, Hybrid, Electric assist, Kids... we've got them all. Probably the best selection in a single location you'll find anywhere on the peninsula too.
Got a bike that needs repairs?
We can handle that! If you purchased your bike from us, remember that you can bring it in anytime, without calling ahead, for minor on-the-spot adjustments of brakes, gears and wheels (at no charge; this is included with any bike purchased from us). For flat tires, again, no appointment needed. Where possible we try and do flat tires while you wait, but there will be times that's not possible. At most you will be leaving your bike overnight. For normal (bigger) repairs, calling ahead to schedule an appointment might make sense because the repair backlog at better shops sometimes goes from overnight to two weeks in the blink of an eye!
It's E-Bike time at Chain Reaction! Test-ride an E-Bike and win! We have scratcher cards available for everyone who test-rides one of our awesome E-Bikes. Everyone wins something. Could be a water bottle, flashing safety lights or, $200 off any E-Bike. E-Bikes are the latest thing; find out why! Commute to the office without needing a shower, bring home the groceries (even if you live on top of a hill!) or keep up with your obsessive-cyclist partner. Prices start at just $1299 (Oyama folding E-bike) up to the incredible Trek Super Commuter 8 at $5199.
